Power of a Number using Recursion

Detailed guide and Python implementation for the 'Power of a Number using Recursion' problem.

問題提起

Write a function power(base, exp) that computes base raised to the power exp using recursion. The function should take two integers base and exp as input and return the result as an integer. Assume exp is always non-negative.

制約
  • 0 <= exp <= 20
  • -10 <= base <= 10

Example 1
Input
base = 2, exp = 10
Output
1024
Explanation

2^10 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 = 1024

Example 2
Input
base = 3, exp = 4
Output
81
Explanation

3^4 = 3 * 3 * 3 * 3 = 81

Example 3
Input
base = 5, exp = 0
Output
1
Explanation

Any number raised to the power 0 is 1

Need a Hint?
Consider using Recursion-specific data structures like sets or heaps.
Edge Cases to Watch
  • Empty input structures
  • Single element inputs
  • Large numerical bounds
